When a Student Performs an Endothermic Reaction in a Calorimeter

question 74

Multiple Choice

When a student performs an endothermic reaction in a calorimeter, how (if any) does the calculated value of ΔH differ from the actual value if the heat exchanged with the calorimeter is not taken into account?

• A) ΔH_calc is less positive because the reaction absorbs heat from the calorimeter.
• B) ΔH_calc equals the actual value because the calorimeter does not absorb heat.
• C) ΔH_calc is more negative because the calorimeter always absorbs heat from the reaction.
• D) ΔH_calc is less negative because the calorimeter absorbs heat from the reaction.
• E) ΔH_calc is more positive because the reaction absorbs heat from the calorimeter.
